William McIntyre was Grace Cahill's most trusted advisor for years. With a family as rotten as hers, it's understandable why she would turn to someone outside of the circle for loyalty and guidance. (It's difficult to ask cousins for favors when they keep trying to murder you). But was William keeping a major secret from Grace about his heritage? Or if Grace knew, why was she purposefully misleading everyone else? What was William really doing on all those "business" trips he took on Grace's behalf?
